Programming: Cutelyst, C/C++, Perl and Python

• Cutelyst 2.13 and ASql 0.19 released – Dantti's Blog

  Cutelyst the C++/Qt Web Framework and ASql the ASync SQL library for Qt applications got new versions. Thanks to the work on ASql Cutelyst got some significant performance improvements on async requests, as well as a new class called ASync, which automatically detaches the current request from the processing chain, and attaches later on when it goes out of scope. With the ASync class you capture it on your ASql lambda and once the query result arrives and the lambda is freed and the ASync object gets out of scope and continues the processing action chain.

• LLVM Lands Very Basic Support For AMD Zen 3 CPUs

  While AMD has landed Znver3 support in GNU Binutils, the company hasn't yet sent out patches for either the GCC or LLVM/Clang compilers in setting up the Zen 3 target with its new instructions or optimized scheduling model / cost table. But a basic implementation has been merged to LLVM for allowing "-march=znver3" based on the limited public details thus far. Merged to mainline LLVM 12 yesterday was a basic implementation allowing for -march=znver3 targeting that basically flips on the new instructions known to be supported by Zen 3. Beyond Zen 2, it flips on INVPCID, PKU, VAES, and VPCLMULQDQ. There are also a few other instructions supported by Zen 3 as outlined in this earlier article.

• CY's Take on PWC#083 | Moments on Perl or other Programming Issues [blogs.perl.org]

  I found that I use "and/or" quite frequently in writing. I know, (mathematical-)logically we only need "or". It seems to me to be a language tricky part as the use of gender neutral terms.

• Warning about Python3 update in latest -current | Alien Pastures

  Warning for people running Slackware-current and have 3rd party packages installed (who doesn’t) that depend on Python3. That includes you who are running KDE Plasma5! The “Sun Oct 25 18:05:51 UTC 2020” update in Slackware-current comes with a bump in the Python3 version (to 3.9) which is incompatible with software which already has been compiled against an older version of Python3 (like 3.8). I found 26 of my own packages on my laptop that depend on Python3 and they are all probably going to break when upgrading to the latest slackware-current. This includes Plasma5 ‘ktown’ packages but also several of my DAW packages.

System76's Pop!_OS 20.10 and More Preinstalled GNU/Linux

• Pop!_OS 20.10

  Today we are looking at Pop!_OS 20.10.  It is based on Ubuntu 20.10, Linux Kernel 5.8, Gnome 3.38, and uses about 1.1GB of ram when idling.

• This Linux laptop is a beast - Juno Computers Neptune 15 First Impressions

  I received this beast on tuesday. It's made by a company you might not have heard of, called Juno computers. They operate ouf of London, and much like Slimbook or Tuxedo, they offer laptops based on Clevo designs, as well as desktops. Disclaimer: I haven't received any money for this video, and I don't get to keep the laptop either, so be nice ;)

ScummVM Android Love

Our new and shiny Android port for ScummVM v2.2.1 is now live on the Google Play Store. After quite a long period of dedicated work from our team developers, and a month of public beta testing by members of our community who helpfully reported quite a few issues for us to address, we are finally ready to give you the stable release for our ScummVM Android app. This app has been significantly re-written and tested on modern Android devices, running up to Android 10+. It includes new features which bring it up to speed with the desktop ScummVM application, such as FluidSynth support, Cloud Saves and more localization choices for the UI. Also included is the Local File Server (LAN) feature, whereby your device can act as a temporary file server allowing you to download files (eg. save files and even the config file) or upload new ones (eg. game data) using a web browser from a PC or another client.

Kernel: Linux 5.10 Outline, TTM and Intel Compute Stack

• Linux 5.10 Brings Many Changes From Better CPU Support To File-System Optimizations - Phoronix

  The Linux 5.10 merge window is set to close this afternoon followed by around seven weeks worth of release candidates before the stable kernel release in December. As usual here is our look at the many new features set to premiere with this next version of the Linux kernel. With Linux 5.10 there is a lot of work on file-system optimizations and other storage improvements, various additions for AMD Zen 3 processors, continued open-source driver work for Big Navi / Radeon RX 6000 series, mainline support for the Purism Librem 5 smartphone revisions thus far, the Creative SoundBlaster AE-7 support finally being supported under Linux, XFS has shifted its timestamp support from breaking after Year 2038 to now working up to Year 2486, Nintendo Switch controller support, and other new hardware support and other work.

 

• New TTM Code Can Yield 3~5x Faster Page Allocation For AMDGPU, Other Benefits - Phoronix

  The Linux kernel's TTM memory management code that is most notably used by the Radeon / AMDGPU kernel drivers but also Nouveau, QXL, VMWGFX, and others, is seeing a new back-end allocation pool that can yield 3~5x faster page allocation performance for video memory.  Longtime AMD Linux driver developer Christian König has been working on this new TT back-end allocation pool that he posted today. With the patch series it is made the default for TTM and updates all existing TTM-based drivers to using this new allocation code for pages.      

• Alder Lake Support Published For The Open-Source Intel Compute Stack

  This past week Intel began adding Alder Lake support to their Linux graphics driver and that also continued on the compute side with the Intel Compute-Runtime receiving initial support for Alder Lake S "ADLS" too. The open-source Intel Compute-Runtime that provides OpenCL and oneAPI Level Zero support for Intel graphics hardware on Linux merged their initial Alder Lake code this week. But given that Alder Lake is still using Gen12-LP graphics like Tiger Lake and Rocket Lake, the enablement isn't too great but just some basic modifications and tweaks while largely leveraging the existing Gen12 paths, just as we've seen with the kernel DRM driver, etc. The Alder Lake support for the open-source Intel Compute-Runtime was merged under "opensource ADLS."
